Abstract

Windowing, or selection of a specific portion of an original document area, is a desirable product feature for an Image Input Terminal (IIT). An area is windowed by defining X and Y coordinates reference points. This information supplies electronic masking around function of the operator's ability to coordinates.

USER AID FOR DOCUMENT WINDOWING FOR AN IMAGE INPUT TERMINAL (Cont'd)

Windowing, or selection of a specific portion of an original document area, is a desirable product feature for an Image Input Terminal (IIT). An area is windowed by defining X and Y coordinates
reference points. This information
supplies electronic masking around
function of the operator's ability to
coordinates.

of that area relative to established system is manually keyed into the MPU which then the defined area. "Correct" windowing is a accurately identify and define the locational

This proposal details a unique method for simple and accurate operator definition of a document window area. And, the proposed method satisfies windowing specification requirements and inherent functional constraints for both moving platen type IITs and those employing a constant velocity transport (CVT) for moving the document being scanned across a scan slit.

Referring to Figures 1 .- 3, the proposed method incorporates a user ''aid" in the form of an accessory 5 which would be provided for an IIT and which is comprised of two pieces 6, 7 of flexible, clear material "hinged" at one end 8. The accessory sheet size would correspond to maximum document scanning capabilities of the IIT and would contain the following graphics: (1) maximum X and Y direction document size lines 9, 10, (2) Y-registration...
